Convection
A.
|
Boundary where two plates move away from one another |
|
| B. |
The crust and the stiff upper mantle combined; this is broken into plates |
| C. |
The growth of volcanoes from the ocean floor due to oceanic-oceanic convergence |
| D. |
Rising of warm material due to lower density |
| E. |
Boundary where two plates slide past one another |
| F. |
The subduction of denser lithosphere beneath more buoyant continental crust |
| G. |
Boundary where two plates move towards one another |
| H. |
The “weak layer” within the mantle. Motion here is thought to help drive plate tectonics |
| I. |
The downward movement of sediments and oceanic crust at subduction zones, which generates molten material |

|
| B. |
A broad upwarped feature that is roughly circular or oval-shaped when viewed from above |
| C. |
The spot on Earth’s surface directly above a fault where movement takes place during an earthquake |
| D. |
The folding of rock due to overlying pressure |
| E. |
A fold that is highest in the middle |
| F. |
Long, low cliffs produced at Earth’s surface where a fault’s vertical offset is exposed |
| G. |
A fold that is lowest in the middle |
| H. |
The fracture along which blocks of rock move relative to each other |
| I. |
Changes in rock shape due to stresses that exceed the strength of the rock |
Question 8
Baja, California separates from Mexico
Pangea intact
India collides with Eurasia to form the Himalayas
The separation of North America and Africa
Southeast Asia joins with Eurasia
The separation of Africa, India, and Antarctica
Question 9
The past few years have been active ones for earthquakes as evidenced by the devastating quakes that occurred in Haiti, Chile and Japan. Are large earthquakes becoming more frequent, perhaps because they set off tremors that can cause further activity? Scientists are currently debating this issue. And if large earthquakes become more frequent, will the U.S. be properly prepared to respond to one within its borders quickly and appropriately? Do you think that large earthquakes are really increasing in number at present? Why or why not (please be specific in your answer to the question)? If they are, do you think the U.S. will be prepared and ready to cope with the challenges?
Your response should be at least 200 words in length
